Coprological Prevalence And Associated Risk Factors Of Bovine Fasciolosis In And Around Zenzelma, Bahir Dar, Ethiopia

Abstract

A cross-sectional study was conducted to know fasciolosis prevalence in cattle plus identifying the risk factors associated in and around Zenzelma town, Bahir Dar Zuria woreda, west Gojam administration Zone. The study was done in 2016. Parasitological examination of feaces collected from 192 cattle and examined using fecal sedimentation technique to understand fasciolosis prevalence was done. The study observed 26% prevalence at the study area. Associated predisposing factors taken are; site, sex, breed and age did not show a significant effect for the infection to occur (P>0.05). However, there was a statistically significant association of fasciolosis beteween body condition of cattle's (p<0.05) in which 38.8%, 27.3% and 10.2% of prevalence obtained in poor, medium, and good body conditions respectively. It was noticed that a highest prevalence rate of 38.8% was recorded in poor body conditioned animals. The study observed that the incidence of the infection was varying between study sites (i.e. 28.7%, 22.1%) in Gediro and Sifatra respectively. The current finding shows that fasciolosis in cattle is among the most economically important parasitic disease affecting cattle and common in areas around Bahir Dar. Hence, control strategies should be designed to minimize the occurrence of the infection.

Study of Prevalence and Associated Risk Factors of Bovine Fasciolosis in Jimma Horro District of Kellem Wollega Zone, Western Ethiopia

“…The prevalence of 27.6% of bovine fasciolosis was found in fecal examination in Jimma Horro district. This result is in line with [14] and [3], who reported that 26% and 30% prevalence of bovine fasciolosis in Bahir Dar and Dangila, Ethiopia, respectively. This result was also similar with report of [2] with 27.2% prevalence of bovine fasciolosis in Hawassa; [25] 33.42% in North Gonder and [9] 36.72% in and around Bahir Dar.…”

“…Chronic fasciolosis commonest form of the disease in cattle and one of the sign is weight loss (emaciation) [22]. This finding is consistent with some previous studies in Ethiopia [3,14], who stated that prevalence of fasciolosis was statistically significantly associated with body condition in cattle.…”

“…The spread of the fasciolosis largely depends on the intermediate host's ecology (genus Lymnaea). Lymnaea natalensis, aquatic snails is important for F. gigantica whereas L. truncatula, an amphibious snail with wide distribution throughout the world, is an intermediate host for F. hepatica [14].…”

“…This information is very important in planning control programs and also estimating the economic burden to the country as the result of this parasite [15]. Bovine fasciolosis has direct economic impact in increasing condemnation of liver, but far more effects are decreased animal productivity, lower calf birth weight and reduced growth in infected animals and cost of animal treatment [14]. Moreover, the economic losses due to fasciolosis are included mortality, morbidity and increased susceptibility to secondary infections and the expenses of control measures [33].…”

Study of Prevalence and Associated Risk Factors of Bovine Fasciolosis in and Around Ambo District Abattoir and Field Survey Western Ethiopia

“…There was statistically significant association among age of the animal and prevalence of fasciolosis (P<0.05). Similarly, several studies in Ethiopia [31,32,24,5] reported age as one of the important risk factors influencing bovine fasciolosis in cattle. The increased resistance (low prevalence) as age increases is most likely related to the high level of tissue reaction seen in bovine livers, severe fibrosis which impairs the passage of immature flukes, acquired resistance.…”
